The naughty people at Christian Dior have been given a slap on the wrist for ‘misleading’ consumers with a cosmetics ad.

Starring Natalie Portman, the ‘miracle’ mascara promises to ‘deliver spectacular volume-multiplying effect, lash by lash’.

But the Advertising Standards Authority (ASA) weren’t buying it – and yesterday banned the ad for being unrealistic.

A statement released by the ASA said: ’Because we considered that we had not seen sufficient evidence to show that the post-production retouching on Natalie Portman’s lashes in the ad did not exaggerate the likely effects of the product, we concluded the ad was likely to mislead.’

Dior admit to ‘minimal’ retouching.

You can judge for yourself – the before ad (below) clearly shows the difference but then again we all know most advertising is subject to Photoshop these days.

But it is nice to know we can relax when our ‘miracle’ products don’t give us spider-leg lashes, flawless skin and perfect hair….
